The Paramount 310 has updated image files that the other sets require, so once you install the latest version of the 310 the 320, 332 and 450 the will load without issues.

If you have downloaded the Paramount 310 since the last update on September 29, 2012 then you do not need to download it again as you have the latest version already, if you have downloaded the 310 prior to this time please download and install it again (it will automatically update your installation, you do not need to uninstall the previous version first) so that you have the latest updates which are required for the subsequent Paramount series.
